Of course, the uncovered shots are always more exciting. Yours has to be one of the greatest jobs, blowing things up for a living.....and no one gets hurt!
Best thing i can say is SWEET. Most people have never played with explosive besides fireworks. This shows that covering with dirt controls the blast. Thank you for all rhe work you put into videoing and editing this for us all to watch. Stay safe and make little rocks out of big rocks.
At around 8:23, that was some beautiful blue colored stone. I have never seen stone that color before. There is nothing better than watching Dave`s handy work in all of it`s glory, out in the bush.
This is one of your better videos Dave, so much more exciting when it is not all covered up with dirt to see the effects of the blast. So much power, unbelievable. What also is interesting is watching the delays work in the slow-motion videos. I can see how you control of the force and direction of the blast using the delays, most interesting.
Always a pleasure watching pros at work. As one who's walked and cycled on many similar roads, I now have a greater appreciation of what it takes to maintain them. Many thanks and stay safe!
Thanks for watching 534, few people realise how much upkeep against erosion etc. is required for seldom used forest roads, most of these roads started life as log tracks and now serve as fire access roads and as such they must be ready to carry heavy vehicles at any time.
Be brave camera.! 😊 This really shows what the cover dirt does and how much SAFER it is with it! But it sure is a lot of fun watching these just going wide open! 😊 Thanks for sharing and take care. 👍
Thanks for watching Ken, This is a good one for me to show the earth moving guys that I work with when they say "do we really need to put all that dirt over it"
@@demolitiondavedrillandblast The short answer to them is Bloody Oath you do! Unless they are offering to catch any flying rock before it hits something important and or expensive.
Thanks for getting on board James. OK thanks for asking, if you are regularly working with stone dust, especially hard igneous rocks that contain a lot of silica, you need several levels of protection if you want to live a long time, you need to treat this stuff like it is asbestos. The only reason that there is a contractor vacancy in my area is because the last guy died of silicosis in his 40's after a failed heart / lung transplant, and he always used a mask they tell me, but he was evidently not very good at managing the secondary exposure risks. So rule number one suck up and capture as much as you can.
Impressive to see what happens in these uncovered blasts! Now I understand better why you pack a meter or more of dirt on the rocks you handle in residential areas. Keep on banging, boys!
Easiest entry point would be underground mining, the pay is good. Entry into my kind of blasting is near impossible unless your born into a family business as nobody will give you work without being able to prove a lot of experience and you won't be able to get public liability insurance without a long track record of safe work. You could gain some experience by labouring as a driller.
Just wanted to let you know how much I enjoy your videos, and wanted to compliment you on how much your videography? skills have improved - multiple angles, drone footage, slow motion, slow motion drone footage - love your work, and keep it up, stay safe. PS - hope you enjoyed browsing through the wipe category in your video edit software - next time, star wipe. :)
Excellent slow motion vision, it really demonstrates the effect of the in ground delay in the signal tube dets. When will Pyro Paul earn a pair of red coveralls?
Hi Dave, Another awesome video! Your fast-mo & slow-mo is wonderful. Great to see some of that rock fly!! Many thanks for all the extra work you go thru to provide interesting videos!! Arizona Jim
Thanks Mark, I can't tell you off the top of my head as most of the music I use comes from only 3 or 4 artists... but not this one, I'll have to fire up the other PC and dig up the Premier Pro file and have a look.
I am wondering if it would be possible, should you undertake a similar job of widening a road in the not-too-distant future, to have 'before' and 'after' images to compare what the finished work looks like to what it was like when you first arrived on the scene.
Im curious if it would make much difference in blast performance if quick setting expanding hydraulic cement was used as stemming instead of the typical fine crush. Some shot gunning can be seen in the video as the stemming is blown out of the hole.
I don't think that you would want to be using the expanding variety in case it placed pressure upon the explosives down in the bore hole. The idea of a more secure cap to the holes does merit investigation.
I believe cement does work well, but if you should need to remove it, e.g. to treat a misfire, then you have a problem. Many of the holes in this video shoot their stemming because the hole is just too short for the stemming to work effectively - the short holes only have around 13 hole diameters stemming length, a good starting point in blast design is 25 times the hole diameter.
I find a lot of evidence of failed attempts to break the rocks with hydraulic hammers and 4 times now I have found blast holes of people that have come before me, that's where it gets interesting, one time with wires coming out of the hole... Another very good reason to clean it up and have a good look before you start drilling!
LOL was the road gang following behind you clearing the rock off the road or was the road closed? Love you not having to cover for the blast and the high speed cam shots are great.
Hi Joe, took me a while to re find this video, this is the best explanation that I can find on how we got all these rounded edge rocks - ruclips.net/video/nFcTCtNWr5Y/видео.html
Yes and no, shaped charges on rock is very wasteful in that you need a much much larger mass of explosives and in most cases the noise is prohibitive. This method is sometimes used to quickly clear large boulders that have blocked a road etc.
Never really tried that Bruce, I have heard that some people believe that every hole should be filled right to the top... maybe I should try that some day when I have a very large buffer zone.
Dave's paying by the KG for the supplies, so using less affects the bottom line. I'm guessing s long as a machine can come through move the bits, then the contract is deemed fulfilled and thus billable.
I guess there is no need to use blasting mats if you are way out in the bush. And in Canada we use the term " the bush " unlike the Americans who would use the terms " the woods " or " the forest ".
Thanks for watching Bob, we also use Forrest, don't use "the woods" much but have other terms like "out in the scrub" - usually used for Malle bushland and also "out in the sticks"
The detonators used here have a 400ms in hole delay, the reason behind this is so that you can fire a number of holes in quick sequence and not be concerned about rock movement cutting off the signal tube or wires in an adjacent hole, this may still happen but it is no longer a show stopper because the detonator in this hole has already been initiated and the 400ms timer is counting down to fire.
@@demolitiondavedrillandblast ah so thats why! Cheers mate! Bloody good fun watching you work leaving me more and more impressed on how precise the cuts are, like "The Squeese". All the best wishes from cold and wet Norway! 🇳🇴
For comparison, are you loading this rock about the same as your average residential job? Or do you load these hotter to need fewer holes? I am wondering if the blast force is the same when you have them covered, or if this is hotter.
Hi Ben, Mostly the same loads, some of them a little bit hotter ~20%. The dirt does a pretty good job of moderating the blast hey! Something else worth consideration is the the rock needs considerably less explosive to break it when it is not covered as much of the blast energy in the compression wave is dissipated into the soil cover where as when the rock is not covered, a lot of this energy is reflected back as a tension wave which ads to the destruction. Kind of like an impedance mismatch causing a high VSWR
@@demolitiondavedrillandblast now that's really fascinating! So basically the surface of the bare rock has such a drastic refractive index change from rock to air that the shock wave reflects back, but dirt cover lets the energy escape better, like putting a radiating load on the end of coax? (mixing comparisons lol) I would have expected the weight and compressible mass of the dirt to absorb energy and counter the outward push of the shockwave, but the concept of the internal reflected energy is new and very interesting to me! And I also find it interesting that you seem to also know about radio. Lol But I guess that's not surprising considering your obvious technical aptitude!
Nice video Mate! We like Pyro Paul's Head gear. But where are the corks? Just to let you know that a flood of your videos have come through. That's why I am commenting on them only now. Cheers Mate.
Some of the slow motion footage of multiple shots is like watching ballet moves. Oh & my Pomgolian preconceptions as to what "the bush" is have been given a thorough kicking.
@@demolitiondavedrillandblast Indeed. Here was me imagining miles of dried up scrub with scabby 'roos everywhere & the odd sheep/koala. A mate of mine in Sydney who also watches your channel has just been very rude about Victoria, or "Leper Land" as he called it. Stay safe & pox free matey - love your stuff & how you present it.
WHY IS THERE ALWAYS AN ABUNDANCE OF CORD ON THE DETONATORS.ARE THE CORDS FULL OF A CHARGE OR CHEMICAL? COULD YOU PLEASE EXPLAIN HOW THESE WORK? I NOTICE THERE ALWAYS 2 POPS FOR EACH HOLE.
These are what is known as shock tube or "Nonel" (non electric) detonators, they come with set lengths of shock tube attached to the det. The two pops per hole, first pop is the surface delay clip firing, these connect it all together and set the order in which the holes fire and time delay between holes, second pop is the main charge down the hole firing 400ms after the surface delay clip fires. The shock tube is a thin plastic tube that has an explosive coating on the inside that is not strong enough to damage the tube but only strong enough to carry a shock wave along the tube. These are a lot safer to handle and use that the older style electric detonators.
@@demolitiondavedrillandblast is that because the olde one could self detonate because they were nitro cellulose or something like that? Are you noticing alot more views lately? Lastly could you please show more of the boulder/rock clean-up? Even if it's time sequenced.
Well, can't say that is true in every case, I love my work but it is very physical and I go home at the end of most days fairly knackered - I don't have any trouble sleeping at night. Thanks for watching Dave.
Thanks for watching Michael, yes this job used all non electric or shock tube dets, I would usually use cord for this type of work but there were a few homes near enough to be annoyed by the extra noise of cord.
@@demolitiondavedrillandblast Thanks for explaining. I'm really curious of what components you use and why you choose them. Back in the early 80's I trained for explosives but it was very limited. 2 caps, electric or fuse. One det cord. C4 or dynamite. Not a lot of choices.
I get nervous for your camera every time, one day it's gonna get it hard, and sorry, but It's going to be great. Edit: you could maybe add to the title of these videos "uncovered blasting" when you do it, maybe you have a term for it, I can see these kind of videos going viral, these shots are so cool to watch.
Actually Dave should consider putting a watermark logo somewhere all through his videos to help prevent any video pirates from swiping any video that might go viral. Harder to argue ownership after the horse has bolted.
Don't know if you have ever done stuff in mines, but I was watching videos on old abandoned caves, add to that my relatives are opal miners and I got to thinking ,,,,,,, I know , never a good idea , but those little dingo diggers, they would fit in a mine, they would easily replace the little rail cars and the shovels that you load them with. Battery and motor technology has come a long long way in the last 50years and those things could do with a great big heavy battery pack in their base. I wonder if they could be fitted with a drill guide or usefully big hammer to let a single man be more effective underground.
Bruce I watched a opal mining video a couple of years ago and they do use a machine a bit like a Dingo but fitted with a horizontal rotating drum which has diamond pick points mounted to it. The machine can be used to cut full height passage ways to follow the opal vein lines or to create underground rooms. I think it was powered by a small diesel engine with a small flexible exhaust hose running up to the surface. JCB have recently introduced a range of battery powered equipment designed for confined space working that could also be very useful for working underground.
Hi Bruce, the Brokk and Husqvarna range of remote control demolition robots could be good for this as you can operate them from a safe distance and they are electric
@@markfryer9880 Thanks. It's great to hear of these things and I am not just off in fantasy land. JCB are good gear anyway and full electric for confined spaces makes the workplace even better
Yeah... cracked another front screen on Osmo #1 yesterday, The guy was using a breaker on the excavator and the camera was too close and was hit by a fast moving stone chip. The main issue is because the lens is such a wide field of view, everything looks a long way off so I have to put it very close to the action.
@@demolitiondavedrillandblast That camera is continuing with the theme of _2019: The Year Of Living Dangerously_ - the tripod took a hit around 7:04, and looking at the trajectory of some fragments at 15:22 I was amazed it survived!
The fastest rock is the small size stemming rock that gets ejected out the top of the hole sometimes, when this happens and you are using blast mats it just shreds the rubber mats and goes strait through! One way to protect your blast mats is to cover the holes with a thick square steel plate but these also get badly bent over time.
"No trees or cameras were harmed in the making of this video"... well almost, the drone got a dislocated gimble and damaged flex strip when it tried to give a tree a hair cut.
Yeah, I'm also surprised that they survived, the DJI Osmo action camera is a small target and looks like it is made to take some rough handling, the Sony Handicam is quite vulnerable though
There would have been more drone video on this one but it got stuck in a tree and I had to climb up and shake it out, as a result it sustained a small amount of damage.
Of course, the uncovered shots are always more exciting. Yours has to be one of the greatest jobs, blowing things up for a living.....and no one gets hurt!
Couldn't agree more!

Exactly.

They well knew what to expect.
I has got to be difficult/challenging going from a job like this where you can use extra force to a breaking up rock next to a house in the city...
Not really, just like driving at highway speed and then slowing down to go through a town.
"There's A Bit Of Hard Rock In The Way "....Not for bloody long their isn't!!😂😂😂Hahaha!!😀👍
Yep!
14:28 That's not near Store Creek is it?
Where is Store Creek?
@@demolitiondavedrillandblast In East Gippy, about 20k NE of Bairnsdale. Great video by the way mate!
I get nervous for your camera every time, one day it's gonna get it hard, and sorry, but It's going to be great.
Edit: you could maybe add to the title of these videos "uncovered blasting" when you do it, maybe you have a term for it, I can see these kind of videos going viral, these shots are so cool to watch.
I agree.
Actually Dave should consider putting a watermark logo somewhere all through his videos to help prevent any video pirates from swiping any video that might go viral. Harder to argue ownership after the horse has bolted.
@@markfryer9880 Actually Mark, RUclips does a pretty good job of notify me when this happens.
Don't know if you have ever done stuff in mines, but I was watching videos on old abandoned caves, add to that my relatives are opal miners and I got to thinking ,,,,,,, I know , never a good idea , but those little dingo diggers, they would fit in a mine, they would easily replace the little rail cars and the shovels that you load them with.
Battery and motor technology has come a long long way in the last 50years and those things could do with a great big heavy battery pack in their base.
I wonder if they could be fitted with a drill guide or usefully big hammer to let a single man be more effective underground.
Bruce I watched a opal mining video a couple of years ago and they do use a machine a bit like a Dingo but fitted with a horizontal rotating drum which has diamond pick points mounted to it. The machine can be used to cut full height passage ways to follow the opal vein lines or to create underground rooms. I think it was powered by a small diesel engine with a small flexible exhaust hose running up to the surface. JCB have recently introduced a range of battery powered equipment designed for confined space working that could also be very useful for working underground.
Hi Bruce, the Brokk and Husqvarna range of remote control demolition robots could be good for this as you can operate them from a safe distance and they are electric
@@markfryer9880
Thanks. It's great to hear of these things and I am not just off in fantasy land.
JCB are good gear anyway and full electric for confined spaces makes the workplace even better
Nice!!! ( love the "woodsie" shots!)
Me too.
That is cool in slow mo. Love your accents.Interesting video. Thank you
:-)
How many times have you shot that drone down? Nice work, guys.
Got it stuck in a tree on this job... good thing I'm pretty good at climbing trees.
Those cameras are living on borrowed time out in the sticks!
Yeah... cracked another front screen on Osmo #1 yesterday, The guy was using a breaker on the excavator and the camera was too close and was hit by a fast moving stone chip. The main issue is because the lens is such a wide field of view, everything looks a long way off so I have to put it very close to the action.
Funny in that over here in the US we also call the out of city stuff, out in the sticks.
the greenies would be having a fit if they knew you were blowing up the rocks lol
Most of the greens are red on the inside and I don't care too much for them
AWESOME!!!!
Thanks for watching Richard, more than 120 videos to chose from.
Your going to have to move the cameras a lot closer so we can see one get hit, i think i speak for the majority looking at your excellent videos. LOL
Maybe you would have a sacrificial camera that I can use???
@@demolitiondavedrillandblast That camera is continuing with the theme of _2019: The Year Of Living Dangerously_ - the tripod took a hit around 7:04, and looking at the trajectory of some fragments at 15:22 I was amazed it survived!
Demo Dave, Pyro Paul? I'm baggsin' AmPho Alex.
You join the ranks of "Blast mat Bob" and "Detonator Dan"
@@demolitiondavedrillandblast Greatest Hard Rock Band ever...
@Roger Rarebit yeah. I was drunk.
@@AlexJBaldwin Bit like getting a tattoo when you are drunk and you get it wrong.
You're stuck with AmPho Alex.
Sorry mate! ;-)
i wonder How Many Feet per second the Rocks travel at ??
The fastest rock is the small size stemming rock that gets ejected out the top of the hole sometimes, when this happens and you are using blast mats it just shreds the rubber mats and goes strait through! One way to protect your blast mats is to cover the holes with a thick square steel plate but these also get badly bent over time.
Nice Job Dave, ….but have you ever considered that one day you'll run out of bits of Australia to blow up ;-)
Given just how bloody big this country is, Dave won't ever run out of rock to blow up.
We have this really really big rock smack bang in the middle of Australia that I have my eye on.
@@demolitiondavedrillandblast now now Dave landmarks are off limit but, it would be nice to it blow lol.
@@scruffy6151 That big rock is off limits to all white fellas now and we are no longer allowed to climb it.
@@demolitiondavedrillandblast well then might as well make it alot smaller lol.
Demolition Dave and Pyro Paul :)
I have been helping Paul again... video coming soon.
Brave cameras!
As Bachman-Turner Overdrive once said, "You Ain't Seen Nothing Yet"
what are you using to blast with ? were any trees are cameras harmedin the making of this?
"No trees or cameras were harmed in the making of this video"... well almost, the drone got a dislocated gimble and damaged flex strip when it tried to give a tree a hair cut.
Why don't you show the results of your demolition charges? It would give a clearer understanding of what you have done and how you did it.
I often do, check some of my other videos Bushy
Do you ever find gold
Sadly no.
That last one had a big gooly the size of a football heading for the camera but went clean over, you can see the shadow.
Yeah, I'm also surprised that they survived, the DJI Osmo action camera is a small target and looks like it is made to take some rough handling, the Sony Handicam is quite vulnerable though
It reminds me of IEDs over in the sand box.
i wonder if there are any kids out there that are thinking i wanna be a demo guy
Oh yeah.
I am sure there are alot of adults also.
@@scruffy6151 Guilty as Charged.
Play that back at .25 speed, wild!
Dam oh&s..... Love the vids
This was safe, the road was blocked both ends, everybody was notified and well clear.
WOW just a little bit to much on the first one lol, ps love the over head videos
There would have been more drone video on this one but it got stuck in a tree and I had to climb up and shake it out, as a result it sustained a small amount of damage.
terbaik boss ku
Whatcha doin? Just watching Dave blow shit up on the internet. :-)
It is a very blokey thing, my viewer statistics tell all, female viewers are
You ruined their nice gravel.LOL
Naw, he just added some, although it was a wee bit larger in size! 😊
